PAPER BAG.

SPECIFICATION forming part of Letters Patent No. 514,889, dated February 13, 1894.

Application filed October 11 1893. Serial No. 487,315- (No model.)

To all whom it may concern.-

Be it known that I, JOHN MURRAY. GUIL-.

BERT, a citizen of the United States, residing in the city and county of Philadelphia, Stateof Pennsylvania, have invented a new and useful Improvement in Paper Bags, which improvement is fully set forth in the following specification and accompanying drawings.

My invention relates to an improvement in paper bags of the order of that shown in Letters Patent No. 432,308, granted to me onthe th day of July, 1890, and consists in forming the body of the bag with a tuck to receive the mouth thereof, and thus lock the bag in 15 closed condition.

. It also consists of the general construction of the bag, as will be hereinafter set forth.

Figures 1 and 2 represent views of opposite sides of a paper bag embodying my invention, the same being in open condition. Fig. 3 represents a view of the bag partly closed. Fig. 4: represents a view of the bag fully closed. Fig. 5 represents a section online or, m, Fig. 4. Fig. 6 represents a view of the z 5 piece of paper from which the bag is formed. Fig. 7 represents a perspective View of the bag while the contents are being discharged.

Similar letters of reference indicate corresponding parts in the several figures. o Referringtothedrawings:Adesignatesthe body of a paper bag; B the mouth thereof, and C the securing tuck for said mouth. The body is formed of the side pieces D, E, the overlying piece F, the flaps G at the side and 5 bottom of said piece F, and the reinforce H at the top of said piece. The mouth B is formed of the pieces J and K, which are upward eontinuations of the side pieces D, E.

In the formation of the parts of the bag as 40 above stated, I take a piece of paper of substantially the shape shown in Fig. 6, and fold the piecesD and E on the line L. Then fold the reinforce H on the piece F on the line M, and next fold the piece F over the side D on 5 the line N. The flaps G, G, are now folded on the outside of the side E on the lines P and Q, and secured to said side E by suitable adhesive material. It will now be seen that the top of the piece F is open,-and forms with the piece D, back of it, the tuck O. The

folded pieces D and E, and J and K, now assume the form shown in Figs. 1 and 2, and the same is creased on the oblique lines R, R, as the division of the body and mouth. I

.also crease the mouth on the lines S, which form an angle with the crease-lines R. When the body is filled, the mouth is turned down on the body on the line B, and its upper part turned sidewise on the line S, which places it over the tuck G into which it is inserted, thus lockingthe mouth and securely and reliably closing the bag.

'It is evident that when the mouth is withdrawn from the tuck, it may be readily unfolded and opened, whereby the contents of the bag may be discharged, said mouth serving as a spout or scoop for such purpose, as shown in Fig. 7.

- If desired, adhesive material may be applied to either side D or E, or bothsides, as shown dotted at a Fig. 6, in order to secure the edges of said parts for preventing powdered material from sitting through the bag.

In order to cause the mouth B when folded, to easily enter the tuck O, the edges of the same are cut out at places corresponding to the ends of the crease lines S, forming recesses T, the same bending around the folded edge of the body of the bag at the end of said tuck, leaving the month free to enter the tuck, without tearing at said lines S.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. A paper bag consisting of a'body formed of side pieces with an overlying piece, and a mouth formed of a piece continuous of the said side pieces, the top of the overlying piece and the side piece back forming a tuck, said parts being combined substantially as described.

2. A paper bag consisting of a body formed of side pieces with an overlying piece having flaps at the side and bottom thereof, and a reinforce at the top thereof, said overlying piece being folded on one of said side pieces forming a tuck between them, and a mouth piece continuous of said sides and adapted to enter said tuck, said parts being combined substantially as described.

3. A paper bag formed of a body, a mouth at the top thereof, a piece continuous of the side of said body, and securing flaps, said side piece overlying said body and being separated therefrom at top, forming a tuck which receives said mouth when in closed condition, substantially as described.

4. A paper bag formed of body pieces, an overlying piece which is secured to the adja cent side of said body, and month pieces which are continuous of the body pieces, said overlying piece being open at top, forming a tuck, and the parts combined substantially as described.

5. A paper bag consisting of a single blank having the side pieces D, E, the overlying piece F with top reinforce H, and side and bottom flaps G, said overlying piece being so secured to said side D as to form the tuck (3 between them, and the mouth piece J, K, continuous of the said side pieces and adapted to enter said tuck, said parts being combined substantially as described.

6. A paper bag consisting of the side pieces D, E, the overlying piece F, with side and bottom flaps, the said overlying piece F being secured to said side pieces, forming the tuck C, and the mouth piece J, K, having the crease S with recesses T, said parts being combined substantially as described.
